Question 5

What system is the paleospinothalamic and neospinothalamic pathway a part of?

Answer 5

anterolateral system

Question 6

What is the reticular formation responsible for?

Answer 6

attention

Question 7

What structures of the brain are responsible for the afferent part of pain?

Answer 7

• amygdala
• insula
• anterior cingulate cortex

Question 8

What structures of the brain are responsible for attention and cognititon?

Answer 8

• prefrontal cortex
• basal ganglia

Question 9

What lobe is the amygdala a part of?

Answer 9

temporal lobe

Question 10

What is the function of the amygdala?

Answer 10

emotion

Question 11

What causes neuropathic pain?

Answer 11

Damage to a nerve
(DM, shingles, amputations)

Question 12

definition: pain that exists AFTER the stimuli causing the pain is gone

Answer 12

chronic pain

Question 13

What descending systems help with pain modulation?

Answer 13

PAG
locus ceruleus
raphe system

Question 14

The raphe system inhibits ____ input going to the cortex.

Answer 14

C fiber

Question 15

definition: pain from the nerve itself

Answer 15

neuropathic pain

Question 16

(true/false) CRPS is normally caused by a noxious event and is hard to control.

Answer 16

false (not caused by a noxious event)

Question 17

What are the s/s of type I CRPS?

Answer 17

• pain
• redness
• allodynia

Question 18

definition: touching an area and causing pain strictly through mechanoreceptors

Answer 18

allodynia

Question 19

Fibromyalgia affects (males/females) more.

Answer 19

females

Question 20

What is the s/s of fibromyalgia?

Answer 20

TTP pain

Question 21

What are the mechanisms that cause chronic pain?

Answer 21

• wind up
• damage to PNS
• reorganization of the CNS

Question 22

definition: As damage to a nerve tries to regenerate, the axons converge due to not enough myelin separating them (therefore, doubling the effect)

Answer 22

ephaptic transmission

Question 23

definition: a mild stimulus causes an increase in neurotransmitters within the spinal cord due to sensitization of the pathway

Answer 23

wind up

Question 24

In allodynia, the _____ will activate the painful pathway.

Answer 24

mechanoreceptor

Question 25

definition: having trouble distinguishing L from R

Answer 25

Laterality
